Seems like there is a conflict between "parser": "babel-eslint" and the Vue plugin.

Source : https://github.com/vuejs/eslint-plugin-vue/issues/30
Solution described here : The workaround is here: https://github.com/mysticatea/vue-eslint-parser#-options "parserOptions": {"parser": "babel-eslint"} should work.

Here is a complete working .eslintrc.js file (at least on my project):

module.exports = {  
    // Use only this configuration  
    root: true,  
    // File parser
    parser: 'vue-eslint-parser',  
    parserOptions: {    
        // Use babel-eslint for JavaScript    
        'parser': 'babel-eslint',    
        'ecmaVersion': 2017,    
        // With import/export syntax    
        'sourceType': 'module' 
    },  
    // Environment global objects  
    env: {    
        browser: true,    
        es6: true,  
    },  
    extends: [    
        // https://github.com/feross/standard/blob/master/RULES.md#javascript-standard-style   
        'standard',    
        // https://github.com/vuejs/eslint-plugin-vue#bulb-rules    
        'plugin:vue/recommended',
    ]
,}
